SYRINGE.

SPECIFICATION forming part of Letters Patent N 0. 764,996, dated July12, 1904. Application filed July 8, 1903. Serial No. 164,704. (Nomodel.)

To all whom, it may concern:

Be it known that I, THoMAs HENRY ELLIs, a citizen of the United States,residing at New Orleans, in the parish of Orleans, State of ouisiana,have invented certain new and useful Improvements in Syringes; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and. use the same.

This invention relates to syringes in general, and more particularly tothe class of vaginal syringes or douches, the object of the inventionbeing to provide a syringe wherein the discharge will be at the outerend of the nozzle, while the liquid discharged will be caused to returnand reenter the bulb at the inner end of the nozzle, the arrangement ofthe parts thereof, including the valves, being such as to preventsuction at the end of the nozzle and to thoroughly cleanse the vaginaland uterine cavities.

A further object of the invention is to provide a syringe which willclose the orifice through which it is inserted and wherein the length ofthe nozzle or tube may be adjusted to reach to the proper depth, also toprovide a syringe which may be operated to cause the fluid therefrom toinflate the vagina while the patient is in a reclining position.

Other objects of the invention areto provide for easy cleaning of theparts of the syr-' inge and to insure their eflicient operation, anadditional object of the invention being to provide a bulb which may beused as a breastpump.

Further objects and advantages of the invention will be understood fromthe following description.

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is a perspective view showing the syringe equipped for adultuse. Fig. 2 is a longitudinal central section of the structure shown inFig. 1. Fig. 3 is a view similar to Fig. 2 and showing the syringeconstructed for misses use.

Referring now to the drawings, the present syringe (illustrated in Figs.1 and 2) consists of a collapsible rubber bulb 5, the mouth 6 of whichhas a cylindrical bore 7, which extends some distance into the body ofthe bulb for a purpose which will be hereinafter explained, and thewalls of the bulb are suificiently heavy to possess a degree ofelasticity sufficient to permit use of the bulb alone as a breast-pump,the mouth of the bulb being fitted over the nipple of the breast, aswill be understood.

In addition to the bulb 5the syringe includes anozzle 8, comprisingacylindrical casing 9, the outer end of which is internally threaded, asshown at 10, and through the walls of which casing are formedperforations 11, which may be of different sizes, as shown, theperforations extending from a line just short of the outer end to a linesomewhat more distant from the inner end, the outer face of the casingor member 9 being smooth. The nozzle includes also an inner member 12,which is tubular in form and at the outer end of which is the head 13,having its inner end exteriorly threaded, as shown at 14:, to engage thethreads 10, so that said head may act to plug the outer end of themember 9 and prevent flow of liquid into the member 9 around the head.The bore of the member 12 is continued through the head, the outer endof said head being flat to form a valve-seat, and in the cylindricalface is formed an annular groove 15. A soft-rubber cap 16 is providedfor the head 13, which cap has an interior flange 16 adjacent to itsopen end, which engages in the groove 15 and holds the cap yieldablyupon the head.

Upon the outer end of the cap is a hollow reentrant portion 17, having aflat end adapted to close the bore of the member 12, the

position of the flange 16' being such as to hold the cap with the freeend of this reentrant portion against the end face or valve-seat of thehead. In the reentrant portion are discharge-openings 19, the axes ofwhich intersect the axis of the said reentrant portion exteriorly of thecap, so that the several streams thrown through the perforations willradiate from the axis of the nozzle with a most efficient washingaction.

The stem of the member 12 is somewhat shorter than the member 9, and inthe face of said stem, remote from the head, is formed an annular groove20, in which is engaged the flange 21, formed upon the inner face of theminor end of a frusto-eonical valve 22, of rubber, the flared end ofwhich lies normally in contact with the inner surface of the imperforateinner end of the member 9. This conical valve prevents passage of waterbetween the members 9 and 12 in the direction of the head, but permitsof ready passage of water in the opposite direction. The member 9 is ofsuch diameter as to cause it to fit snugly into the neck or mouth of thebulb 5, while permitting it to be readily slipped. into or out of thebulb in the manner and for the purpose hereinafter explained.

The neck of the bulb is provided with an exterior elliptical flange 25,having a concave taper to the free end of the neck, so as to fit intoand tightly close the orifice through which the nozzle is inserted inuse.

In the operation of this syringe the bulb is filled with a suitableliquid, and the nozzle is adjusted in the mouth of the bulb to projectto the proper extent, the cylindrical bore of the mouth insuring closureof all of the perforations 1.1 that are not exterior to the bulb. Thenozzle is then passed into the vagina, the soft-rubber cap preventinginjury to the parts, and when the bulb has been pressed firmly againstthe person it is squeezed, and the liquid is discharged therefrom and,passing through the member 9 at the inner end thereof, passes into andthrough the member 12 into the cap, from which latter it is dischargedthrough the orifices of the cap in the manner above described. In itspassage from the member 12 the liquid raises the valve from its seat. Byproper pressure upon the bulb of the syringe the proper force of thedischarge may be obtained. A sufficient quantity or all of the contentsof the bulb having been discharged, the bulb is permitted to expand,when the valve or projection 17 moves back to its seat and closes theouter end of the member 12. At the same time the valve 22 moves fromcontact with the inner face of the memher 9, and suction is set upthrough the member 9, so that the liquid is drawn through theperforations 11 into said member and thence past the valve and into thebulb. This operation may be repeated as often as desired.

In Fig. 3 of the drawings there is shown a form of the invention whereinthe nozzle is of lesser diameter than that shown in Figs. 1

invention.

and E2 and is intended for misses use after menstruation. The nozzle inthis case comprises a short outer member 30, which is adapted to fit inthe mouth of the bulb the same as in the former case, said member havinga closed outer end, save for the perforations 31 formed therethrough.Through the center of the closed end of the member 30 is passed the tube32, having perforations 33 in its outer end to direct the dischargetherefrom, the inner end of the tube having a frusto-eonical valve 34engaged therewith of the same form and arrangement as the valve in theformer construction described. In this form of the invention thedischarge is through the end of the tube 32, the valve preventingoutward passage of liquid through theperforations,whilepermittingreturn-passagetherethrough to the bulb.Liquid may also return through the end of the tube in this form of theWith this construction it will be seen that the various objects of theinvention as enumerated are obtained, and it will be understood that inpractice other modifications may be made, and any suitable materials andproportions may be used for the various parts without departing from thespirit of the invention.

What is claimed is- 1. A syringe comprising a reservoir and a nozzleincluding an outer member having perforations therein, an inner memberhaving a head at its outer end, the said head having an annular groovein its cylindrical face near its outer end, a seat on its outer end, andadapted to engage the outer end of the inner member,

and a cap having an interior flange adjacent to its open end, saidflange being adapted to engage in the groove of the said head to holdthe cap yieldably thereupon, the said cap having a reentrant portion,said reentrant portion being perforated and having a flat end adapted toengage the valve-seat on the outer end ofthe inner member and to closethe bore therein.

2. A syringe comprising a reservoir and a nozzle including an outermember having perforations therein, an inner member tubular in formhaving a head at its outer end, the inner end of the said head beingadapted to engage the outer end of the outer member and a stem, the saidstem being shorter than the outer member and having an annular groovenear its inner end, a frusto-conical valve having a flange formed uponthe inner face of its minor end, the said flange being adapted to engagethe annular groove on the stem, the flared end of the saidfrusto-conical valve being adapted to be normally in contact with theinner surface of the inner end of the outer member, and a cap adapted tobe engaged to the outer end of the said inner member, the said caphaving perforations therein.

3. A syringe comprising a reservoir and a nozzle, said nozzle consistingof a tube having perforations in its outer end and a frustocon icalvalve engaged to its inner end, a cylindrical member having a closedend, the closed end of the said inner member being perforated and boredand rigidly attached near the inner end of the said tube, the flared endof the said frusto-conical valve being adapted to I be normally incontact with the inner surface IQ of the inner end of the saidcylindrical member.
